Apple Bloom was hip deep in Doolots when Scootaloo finally managed to track her down. “There you are, Applebloom!” she said, poking around behind the school’s garden shed to see Apple Bloom mounted up on another filly, going at it energetically. The filly’s ordinary looking bicolored lavender mane hung sweatily on her greyish off-blue head, the horn emerging from it flickering intermittently with a pink glow to the rhythm of their intromission. Her expression was one of wide eyed shock, a clear indication that her rear had only just been introduced to Apple Bloom’s business end.

“Bit... busy, Scootaloo,” Apple Bloom said, slowing in her thrusting enough to look at her friend.

“Heh heh, sorry,” Scootaloo said, waiting for them to finish.

Apple Bloom resumed focusing on the task at hand again when Liza spoke up very shakily, “W-w-wait!”

Apple Bloom gave a disappointed groan, but her hips slowed to a halt and she took another breath and said in a controlled tone that concealed a smouldering desire, “Sure Liza, what is it?”

“It’s... it’s...” With how she was underneath Apple Bloom, Liza couldn’t entirely turn to face Scootaloo, looking at her out of the side of her face. Which, considering they’re horses with huge eyes, isn’t all that much of a problem. “It’s O.K. if she watches?!” Lisa managed to belt out finally. Scootaloo blinked at that, and scratched the back of her head self consciously. She hadn’t thought of whether this might be the sort of thing a pony wouldn’t want others to watch.

But maybe it’d be best to wait until Bloom finished with her to ask Liza what’s up. Scootaloo didn’t say anything else, but walked over beside the two of them so Doolots wouldn’t have to crane her neck so much to see her.

It seems Apple Bloom shared Scootaloo’s confusion, saying “Mmm, why wouldn’t it be?” in a distracted tone, starting up her thrusting again. Liza really seemed intent on this though. You could tell her body wanted her to stop talking and just start taking, but she resisted anxiously.

“Can’t... can’t move and... it’s... safe?” she hissed out.

Apple Bloom slowed up again, and said “Ugh, of course it’s safe. It‒” she humped once eagerly despite her attempts at restraint, “This is mah friend Scootaloo, don’t... don’t worry your... head.”

“I can leave if you want,” Scootaloo offered reluctantly. Surprisingly she really wanted to stay, even though she wasn’t the one getting plowed at all. Her own body was responding pleasantly to this eager action, finding herself drawn to the fascinating join between the two of them, down where Apple Bloom’s shaft rested hidden, or occasionally slid out, gleaming, between them.

“You... you can stay I just...” Liza swallowed, “N-never done this before... just... please don’t laugh.”

Scootaloo did laugh at that, saying, “Are you kidding? You two look amazing! Why would I laugh at that?” Apple Bloom was looking at Scootaloo with a half lidded mask of arousal, her barely controlled hips shoving her dick into the unicorn eratically. That was another thing Scootaloo didn’t understand; it was like Bloom was actually getting turned on by her just being there. Then again, wasn’t Scootaloo feeling the same thing? Maybe not on the same level though. Apple Bloom looked really out of it.

“I-it’s kind of fun to... watch,” Scootaloo admitted feeling a bit apprehensive at saying that. Too often ponies wanted to ruin your fun once they found out you liked it. But Apple Bloom just gritted her teeth and moaned at that, turning to face straight and humping at Liza in earnest. If Liza had any more protests, she sure didn’t voice them. Her voice seemed captured by the same powerful force that was driving her to rock her hips back against the colt wrapped around and inside her.

It really was fascinating how Bloom’s penis just sort of disappeared inside Liza’s grey blue bottom, only to emerge again looking like it could never have fit in there in the first place. Fillies really did have a lot of space in their pelvis, considering. With the physical connection between them, Apple Bloom and Liza almost looked like two parts of one animal, pushing at each other smoothly and in perfect sync. It reminded Scootaloo of a running panther, or a speeding train maybe.

It was also exciting to watch how the two of them subtly changed as they approached climax. Like how Apple Bloom stiffened and her mouth closed tightly. How she stopped watching her hips, and looked into the air, as her thrusts went from deliberate to fluid and automatic. And Liza was no longer just blushing in her cheeks. She had a full body flush that shone on her belly and hindquarters, right through her short blue fur, and the more Apple Bloom went in her, the more she participated in the effort, her hips hiking up and rocking back, working the penis deeper and more firmly inside her. Liza would almost look like she was relaxing, no doubt as the penis shoved the heat out of her mind, were it not for her heavy breathing that turned into wet gasps that were rising in pitch.

Scootaloo found her own hindquarters warming up just at the sight of them doing that, like they had when she listened to the sounds of Apple Bloom and Archer making love. Once again Scootaloo avoided sitting down, trying to ignore it like she had grown reluctantly used to. Scoots still remembered fondly how Apple Bloom’s boy stuff quenched her own burning need... just the other day right? So it’s not like she needed any more or anything. No reason to be greedy after all; the filly known as Scootaloo was already taken care of, and she wasn’t going to let other fillies suffer just because of a little lingering estrus in her. Still, it was making her squirm, not to mention Apple Bloom’s heady scent trickling across her nose, and her interest peaked when Liza’s eyes suddenly opened.

Liza looked back at her own thrusting hips in a frightened wonder, mouthing wordlessly before grunting and throwing her head back, eyes scrunched shut. Apple Bloom moaned and shoved inside her, riding Liza’s rolling hips while Liza’s own thrusting turned into a repetitive jerky stillness, her disarrayed purple tail flopping against the other pony’s side.

“You doing it Apple Bloom?” Scootaloo asked, unable to see what was going on from their hip’s close embrace.

“N‒no she’s jus’...” Apple Bloom slurred with an intense look of concentration as she bit out the word, “Orgasmin’...” Liza could only give a moan in confirmation.

Wow... Scootaloo was actually watching a filly orgasming right in front of her. Not even the most secret affairs of the CMC had managed to reach that stage. Well, Scootaloo had, but she couldn’t exactly watch herself. Sweetie Belle had just massaged her little pillows and occasionally sensually stroked her outer lips. And Apple Bloom had more of an exploratory style, spreading herself and pushing at her depths, a pastern gently touching on her nipples as she sighed happily in pleasure. And that was as far as they’d gotten together.

That was before. Before estrus. Now with this filly quivering and shaking at the drop of a hat, it was clear just how much estrus had awoken them all, changed their bodies over a period of days from wannabes into powerful orgasm machines. Scootaloo remembered herself doing it before estrus, but only after a good deal of determined effort. What once was a challenge to achieve, was now a natural affair that happened so easily you could almost do it by accident. It was even dangerous how easy it was to do, and how hard it was to stop. And something about that was really bucking hot.

What was really hot though, was the moment after that quiet stillness that Scootaloo called orgasm. When the filly Liza’s eyes fluttered open, and her clenching contractions stilled, Apple Bloom started thrusting again. It was just like with Scootaloo. The pegasus imagined, no remembered Apple Bloom driving into her determinedly, Scootaloo’s mind blowing orgasm only egging her friend on. Nothing felt as good as orgasm, but what Apple Bloom was giving Liza now was a continuous sort of stimulation that still felt good enough it kept you from coming to your senses, and that felt wonderful. Scootaloo could only liken her own experience to the thrill of freefall. Liza was totally into it now, shoving her hips back as hard as Apple Bloom was driving hers forward. Liza’s eyes had a droopy lovestruck look to them and she didn’t even care if her tongue lolled out.

When Apple Bloom paused again, groaning and shoving up deep, a realization of something sparked in Liza’s eyes, as her panting turned into a strained moan.

“How about now?” Scootaloo said eagerly. Soon as she did, Apple Bloom started thrusting again though, slowly and with great effort.

“Just... flarin’ up again... almost...” Apple Bloom said hotly, her eyes closed with concentration.

“He got bigger,” Liza gushed, huffing as Bloom swelled up into every inch of her turgid canal.

“Awesome, isn’t it?” Scootaloo grinned at the thought of exactly what Liza was talking about. She had a good idea Apple Bloom wouldn’t last long at this rate. Liza was about to get it good. As if something swelling up big and thick and smooching up against the inside of your cunt wasn’t good enough. Scootaloo shifted uncomfortably on her hoof tips. Her loins were really tickly now. Maybe she shouldn’t be watching this after all, for her own sake. She couldn’t bring her estrus back could she?

“You know I should‒” Scootaloo started just as Apple Bloom gave a strangled shout shoving up deep in Liza and holding there, quivering and straining her hind legs forward. “Are you doing it?” Scootaloo repeated excitedly her earlier doubt forgotten in an instant.

Apple Bloom didn’t answer, but Liza gave a sharp intake of breath and her eyes widened, then turned liquid. “Yes he iiiiiiis,” she announced adoringly. Her cry cut off into a wet gasp when it looked like she lost the fight to contain him. Before Scootaloo’s captivated gaze, the place where their crotches joined squelched and burbled, dripping thickly with Apple Bloom’s trickling seed. If there was any doubt in Scootaloo’s mind, it was gone in an instant before incontrovertible evidence. Though it looked like they were just standing there, Apple Bloom’s seed trickling from Liza’s entrance meant that Apple Bloom had put it into her. Every time a pulse of it squirted out of her, that meant that inside Liza’s unremarkable blue belly, Apple Bloom was pumping it right now.

Scootaloo had to bite back a moan. She thought she was done with this! But in reality she’d been feeling hotter between the legs all day, and she couldn’t deny her body’s reaction to the raw sight of a stallion’s seed. Still, it wasn’t as bad as it was before, so she just had to knuckle through it, right? Whatever a knuckle was. There were so many fillies who hadn’t felt the relief a dick could provide. But Scootaloo imagined wistfully that, if there weren’t so many, then maybe she could get Apple Bloom up against the wall again and‒

“Alright,” said Apple Bloom’s voice as Scootaloo snapped out of her thoughts. Apple Bloom shoved off of Liza, sliding right out of her and causing a pulse of thick fluid to slip out Liza’s vagina as she did. “What’d you need to talk to me about?” Apple Bloom asked Scootaloo brightly, her wet dick dangling prominently between her legs. There was a pregnant pause and Apple Bloom’s eyes widened in shock. She turned to Liza saying guiltily, “Ah’m sorry! Didn’t mean to just... shove off you. Ah mean, you should be all settled now. You don’t need any more, right?”

Liza nodded without turning to face them, waving a hoof and closing her eyes saying, “Sure just... just give me a minute.” She had her hips tilted forward now as if she wanted to keep Apple Bloom’s stuff from trickling out of her by doing some kind of a pony flagon impression. Actually that’s probably exactly what she was doing. But wait, Apple Bloom had said–!

“You can make more??” Scootaloo asked Apple Bloom excitedly.

“Uh, heh, nah I can’t for a while,” Apple Bloom blushed and crossed her hoof saying, “I mean, look at it it’s already gettin’ all small again.” Sure enough, her dick was contracting up into her pelvis with a smooth certainty. “Ah can pump it out uh, 8 or 9 times I think. It’s awful hard to count when I’m doin it. But after that I’m plum tapped out.”

Liza had switched to lying on her back, rocking slightly and making little pleased noises, wiggling her hooves. Apple Bloom smiled at her affectionately and bent her head down to nuzzle at Liza, who pulled herself up on Bloom in a tender hug. It was a sappy sort of gesture that made Scootaloo roll her eyes, but Apple Bloom seemed to like it, and Liza probably wasn’t really thinking all that clearly after that anyway.

And Scootaloo couldn’t deny that when she did it, there had been that kiss...

Apple Bloom was soon sitting with Liza, both of them looking pleased as punch as they leaned against one another. It was so peaceful and endearing a scene that Scootaloo was glad that nopony else came around behind the garden shed here to disturb them. Scootaloo wanted to acknowledge the way it made her heart swell, with a big sappy lovey dovey awwwww, but she valiantly fought the urge down in the name of all that is cool.

“So is that what you wanted to know, Scoots?” Apple Bloom said, looking evenly at Scootaloo. Apple Bloom could look Scootaloo in the eye even sitting down the way she was, with Scootaloo fully standing, once again reminding Scootaloo of how freaking tiny she was. But she didn’t let it faze her, answering quickly.

“No, no I wanted to tell you about Sweetie Belle,” Scootaloo said.

Apple Bloom looked relucantly at Liza then back at Scootaloo again saying, “Is it the sort of thing that can wait a bit?”

“Why’s that?” Scootaloo asked a bit testily.

“Well it’s just,” Apple Bloom looked at Liza again and shifted closer to her, “We gotta talk in private about that, and ah wanted to sit with Liza a bit. When I make the boy stuff it makes me feel so relaxed like and friendly, and I think it does it to a filly too. It’s a great way to make new friends I’d say. So I been taking to sitting together after we finish, just enjoying the feel of it, and being there for her while she’s taking it all in.”

Apple Bloom nuzzled the pony next to her warmly, saying “I really liked being like this here with you, Liza. And I think you like being here with me too.” Liza’s answer was to just silently lean her head against Apple Bloom’s side, a happy sigh going through her relaxed body. Apple Bloom back at Scootaloo apologetically saying, “Y’know?”

“Ugh, gag me with a spoon,” Scootaloo groaned, pantomiming the activity. “You two can have all that sappy huggy stuff to yourself. Just meet me over by the jungle gym when you’re done.” With that she zipped off for the ludicrously elaborate play structure of its namesake.

Apple Bloom lifted her head up and watched Scootaloo leave, somewhat thoughtfully.

“You should go to her,” came Liza’s voice not just in her ears, but radiating from her chest.

“Ah know,” Apple Bloom admitted, laying her head over Liza’s, “But I don’t wanna leave you hangin. I know I helped you, but... you helped me too.” she chuckled, “Emptied me out good.”

Liza giggled in response saying “All I did was stand there, silly.”

“If that’s standin’ then I’m the mare in the moon,” Apple Bloom said wryly, “What I mean to say is, you did good. I really enjoyed doing it with you.”

“Scootaloo helped me too,” Liza remarked.

“Come again?” Apple Bloom asked uncomprehendingly.

“She was there, and she was okay with it and... she made me feel less scared about it. She knew just how I was feeling,” Liza attempted to explain, hesitantly adding, “I had somepony to talk to, when I wanted to say how it was making me feel. I liked that.”

“Guess so,” Apple Bloom said, “I don’t wanna say I’m already old hat though. This is all so new to me too! Twice as much since I wasn’t even a colt a few days ago!”

“You sure are good at being one,” Liza said with a sly smile.

“Maybe ah should try that though,” Apple Bloom pondered. “Find a colt to talk to about how all this is making me feel. I bet he’d understand. I mean I could tell you how good it feels to pump that stuff outta me, or how my penis flaring up feels like a sorta super satisfying stretch, but ...y’know what I mean?”

Liza nodded her cute little round head, saying “I think I kind of get what you’re saying.” She paused and repeated herself, “You should go to her. Scootaloo needs you too.” She paused again and added, “Not just in the penis way.”

Extricating herself from the purple and blue unicorn filly, Apple Bloom stood up tall and looked off to the distance, saying “Ah know, but don’t think for a minute I don’t want to sit with you until your head’s on straight again.”

Liza giggled, “Don’t worry I feel fine. Better than fine, even! Your boy stuff is amazing I haven’t felt this good in... like... ever!”

Apple Bloom smiled at that, looking back at her and saying, “Thanks Liza, I mean for getting my head on straight, I mean, for Scootaloo and all.” She paused a second with a confused expression, then added, “Not just for the penis thing. Are you sure you’re gonna be alright by yourself?”

Liza nodded, standing up herself. She shifted her hips, doing whatever with her passageway in there, but no more of Apple Bloom leaked out of her and that seemed to satisfy her. “I’ll be fine,” she said consolingly, “I need to get back to my friends anyway. I sort of snuck away from them in the um, heat of the moment, and they’re probably worried about me.”

“Alright,” said Apple Bloom, “Just don’t you know, brag about it or nothin’ because like I said ahm tapped out for another I dunno, day or so. Might be able to get more colts involved soon, but they’re a tricky bunch to convince. So, no need to remind your friends of their own estrus problems, for now at any rate.”

“I will try to be discreet,” Liza said in her high fluting voice. “Maybe I’ll wait a few days... see if they notice.”

Apple Bloom laughed, “Well, good luck whatever you do. I’m gonna go find Scootaloo. See you, Liza! Nice meetin’ you!” She gallopped off around the shed then, heading for the jungle gym.

Liza was smiling watching Apple Bloom run off, but her face fell when she heard some familiar words coming from right behind her.

“Well well well. What do we have here?”

The Ponyville Playground Jungle Gym wasn’t exactly the best place to tell your friends to meet at because it was so darned big. You just had to methodically swing on the tire swing up to the first platform, crawl across the net to the west south tower where there was a rattly rope bridge leading to the east platform with the climbing wall, and so on and so forth until you found whoever you were looking for.

As far as places to wait to meet people, it was pretty awesome though. A filly could tire herself out climbing on a tiny bit of the thing and there’d still be more to explore. There was plenty of places to swing on, and plenty of secret forts to defend and just about two ways in and out of everything. Usually more ways out than in because of the liberal application of slides and chutes at every opportunity. Some of them were tricky even. You would think you were crossing solid wood and next thing you know it you’re shooting out to dump on the sand below and you gotta climb up all over again.

Apple Bloom found Scootaloo eventually, busy getting tangled up on the rope netting off in the northeast quadrant. Apple Bloom had spotted Scootaloo from one of the lookout towers, and she climbed inside, then jumped down the two stories one after the other without even hitting the ladders, using her momentum to charge over in that direction, jumping on the ropes head over heels where Scootaloo was with a “Geronimo!”

“Hey Apple Bloom!” Scootaloo said greeting her brightly as the netting bowed and swung crazily underneath them. “That was fast. You didn’t have to hurry I’m fine waiting.”

“Nah it’s OK Scoots,” Apple Bloom said flopping down beside the pegasus, “Liza was real nice about it. I think she knows the value of a true friend.”

“Heh, yeah... we’re um, friends,” Scootaloo said, pulling her hoof out of the netting hole and rolling, which inadvertently, and a complete coincidence mind you, caused her to bump into Apple Bloom. Not that Scootaloo noticed or anything. She was just calm and nonchalant about the warm feel of their markless hips coming in contact with each other.

“So what did you want to talk about?” Apple Bloom asked. She hesitated, and looked around to see if any other foals, such as a gaggle of fillies that she had to take care of, were following or in hearing range. It’d been a good day for her though, and they tended to leave Apple Bloom alone after they saw her going off with a pony, since that meant she wasn’t going to be available for any easy estrus fixings until maybe tomorrow. So they were alone now and could probably talk in private without getting spied on or molested.

“Oh! Um,” Scootaloo’s ear flicked as her smile turned to a frown saying, “It’s about Sweetie Belle.”

Apple Bloom sighed, looking down at her pelvis. It looked so innocuous looking with the dick retracted like that. “She still avoiding me?” Apple Bloom asked unhappily.

“I... yeah,” Scootaloo said listlessly, “I just... I don’t know she’s having... I just really need your advice. I’m no good at this weird relationship problems thing. She’s having a real problem, and I just don’t know what to tell her!”

Apple Bloom looked at Scootaloo worriedly saying, “Did she say anything about what it is?”

“She did a little,” Scootaloo said, “But as soon as she let it slip she clammed up. I don’t think she wants to talk about it.”

“Well she has to talk about it,” Apple Bloom asserted, “Holding somethin in and dwellin on it ain’t a good thing to do. She can’t even tell you though? What did she say?”

“Well I don’t know and maybe I’m saying this wrong but,” Scootaloo fidgeted nervously saying, “She thinks colts are going to make her evil.”

Apple Bloom blinked at Scootaloo unbelievingly before saying, “Yeah, um, you’re gonna have to go into more detail than that.”

“Stallions are making Rarity evil!” Sweetie Belle had said to Scootaloo earlier, while they hid away in their namesake clubhouse.

“Oh no!” Scootaloo yelled, “This is just like that nightmare I had! Quick, we have to find her friends, Princess Luna and Spike’s fire ruby!”

“You had that dream too??” Sweetie Belle asked incredulously. “But no,” she clarified, “I just mean evil, like mean and angry and not being nice to me.”

“Pff,” Scootaloo rolled her eyes, “This is Rarity we’re talking about. That’s nothing unusual.”

“It is so unusual!” Sweetie said in an angry pout, but her face fell into more of a distant fear. “She has stallions come over,” Sweetie said dully, “For her estrus I think. But I thought they were mean to her and made her cry.”

“Which stallions?”

“I don’t know,” Sweetie Belle said uncertainly, “She doesn’t seem to... care? But that’s not it. What it is is that I could help her with those stallions and keep them from being mean, but when I asked she said no!”

“I dunno Sweetie,” Scootaloo said, “What could you possibly do to stop full grown stallions from being mean?”

“Oh lots,” Sweetie said nonchalantly, “I can look at them like this,” and she gave Scootaloo the most heart shattering nose bleeding watery eyed sorrowful look that Scootaloo could possibly imagine. Then Sweetie Belle rubbed her eyes out and smiled saying, “And then they will treat my sister nice.”

“You‒guh, uh, geh,” Scootaloo said, trying to recover from that look.

“So I asked her if I could help her with her stallions,” Sweetie went on undauntedly, “And she just started yelling at me! She said I was just a little filly with a filthy little mouth who is too stupid to know what I’m talking about. And when I asked what I’m supposed to know, she just shut the door in my face. And my horn got stuck!”

“Wow Sweetie,” Scootaloo said, “That‒ that does sound kind of evil.”

“It’s the stallions,” Sweetie Belle insisted. “Rarity is never like this outside of estrus. She’s the best sister I can ever have! But when she started on estrus she wasn’t like this either. She drank her Moon tea and was a good little filly, and played with me and... stuff I don’t really remember, but it was only when she started to be with stallions that she turned into a meanie.”

“Like, what does she do?”

“Well,” Sweetie elaborated, “She’s supposed to be watching me after school and she’s just started locking me outside and making me go play by myself. What kind of sister locks her own sister out of her own Boutique?!”

“Not Rainbow Dash, that’s for sure!” Scootaloo agreed fiercely. Sweetie paused at that, but went on.

“She only spends time with stallions now and never with me, or even her friends. She won’t let anyone help her, and I’m the only one who knows anything is wrong, but everypony just tells me to not worry about such things. And most of the time she won’t be with anypony. She just sits all alone by herself, in the darkness with glowing eyes.”

Sweetie shuddered to herself.

“It’s... not the stallions either,” she said quietly.

“But I thought you said‒”

“I tried to sneak in, but that didn’t work. But I could watch just barely through the window curtains to see what the stallions did, and they don’t do anything mean at all. They just talk with her and then she yells at them, and then they hug for a while and I guess that’s when they put the boy goo in. And a lot of them are nice stallions too I mean,” she blushed thinking of the last, tall, muscular, musky smelling one, who didn’t seem evil or mean, just... tired. “I just think they are... nice...”

“Sweetie...” Scootaloo said uncomfortably, “You have got to be getting something wrong here. Why would Rarity act so mean, when the stallions aren’t even being mean to her?”

“I don’t know,” Sweetie Belle whimpered, “I think maybe... that Rarity might... be broken.”

“Well I can tell something is wrong with her!” Scootaloo announced crossly.

Sweetie continued to explain, “I think there’s something inside her that is evil and bad, and it... comes out when she stays with stallions.”

Scootaloo shook her head, “Nah, that can’t be it. Remember this whole thing about Apple Bloom? I been hanging around her non-stop since she turned into a stallion, and I’ve never felt less like screaming or being mean. You remember how I was when she first did me, right?”

A couple days before that, Scootaloo had zipped back into the classroom, having been dispatched earlier by Cheerilee to find out why Apple Bloom was absent today. It was the strangest day ever for Sweetie Belle. First there was Spike introducing himself, but then there was a real new student just barging in like he owned the place, and it was a colt. He was an amazing colt. He even made Sweetie stop thinking about Button and his boystick I mean joystick I mean joyboy. It looked like the entire class was captivated by him, and Apple Bloom missed it!

Apple Bloom would have loved this colt. He looked like a down to earth farm boy, the kind who bucks apples every day. The kind who would make a filly really happy and would never bring Apple Bloom any harm. He looked like the sunlight that came through the trees on a warm summer day. He‒

“Sweetie, could you get to the part about me already?”

“Hehe sorry.”

After the colt ran out and still no sign of Apple Bloom, Cheerilee had asked the speedy Scootster to go check if she’s alright.

“Scootster?”

“You’re Scooteriffic!”

“Ugh...”

Scootaloo had returned, looking heated and blushing from head to hoof, and she said that Apple Bloom was sick, even though she was lying because Apple Bloom was really a colt, and Scootaloo wanted to give her the special colt hug to make her estrus go away. Sweetie couldn’t really think about that though, because her insides were hot and squirmy, and the Moon tea was making her dizzy so she had to hold back on drinking more for a while. The lesson had been about... something, and she fantasized about asking Button to let her copy his notes, which she never could do because he was a colt and she was in estrus, but she still imagined it.

“This is the weirdest flashback ever.”

“I’m the one having the flashback, so don’t complain!”

“I’m having a flashback too, you know!”

And then after school, Scootaloo had come riding up to Sweetie Belle looking amazing. She wasn’t flushed, and she wasn’t waddling to reduce the stimulation. Sweetie would say she was back to normal, but Scootaloo was even better than normal. She was both energetic and content, like after the time when they went camping. And the reason for this, she was very happy to share with Sweetie.

“Oh, it’s so good to see you!” Scootaloo said hugging Sweetie tightly. “I just found the most super terrific awesome amazing thing! You remember that colt who showed up in class?”

“How could I not?” Sweetie squeaked though she tried not to but it always caught her by surprise.

Scootaloo leaned close and whispered conspiratorially, “It was actually Apple Bloom.”

“What was Apple Bloom?”

“The colt!”

Sweetie’s eyes grew bigger at that, and she started remembering that colt. He didn’t have Apple Bloom’s trademark bow that day, but he had the same lemon yellow coat, and the same bright red curly locks cascading down his shoulders and over his rear. He had looked a lot like Apple Bloom, and even sounded like her if you imagined Apple Bloom as a colt. Sweetie imagined Apple Bloom now as that swarthy, muscular, tall colt, the one who just strutted into class one day without a care in the world. He hadn’t even realized nopony recognized him...

“Nope!” said Pinkie Pie, “One more level and you’re at Inception, and you don’t want to do that!”

“No way,” Sweetie said to Scootaloo unbelievingly, even though the vivid picture in her mind was unmistakable. She couldn’t not see the colt as Apple Bloom anymore. That unbearable tickling in Sweetie’s hips got even stronger thinking about it, just begging her to itch them somehow. She wanted to go find a pole and... and maybe try that for a while.

“Yes way,” Scootaloo said, “And you know what stallions can do about estrus, right?”

Sweetie nodded, then her eyes got even bigger. “You didn’t!” she said, twitching her nose trying to pick up Scootaloo’s hot spicy tang. But it was muted as it had ever been, instead of the way it was with estrus, like shouting into a bull horn. Scootaloo really had done... that! That special hug thing that Sweetie Belle didn’t really understand since the evening hadn’t come yet and Apple Bloom hadn’t done it with her.

“I sure did,” Scootaloo said strutting in front of the small unicorn. “And it was great! She was making my estrus go away even before she used boy stuff on me!”

“How did she do that?” Sweetie asked imploringly.

Scootaloo just winked at her and said, “Well maybe you should stop pining after Button for a second and ask Apple Bloom to show you herself!”

Sweetie looked down at the ground, because it was interesting ground not because she was afraid. “Oh, I could never do that,” she said sadly, “I‒I mean if Apple Bloom really is a colt now I couldn’t just‒I mean...”

“Don’t worry, Sweetie Belle,” Scootaloo said to her, nuzzling her neck encouragingly. “Apple Bloom isn’t any different or colty or anything, she’s just like she used to be before estrus.” Scootaloo added in a whisper, “And she has a boy thing!”

“You’re joshing me,” Sweetie said pertly, whoever Josh is.

“I swear it’s true!” Scootaloo insisted, wings buzzing with excitement. “Here, look!”

“Look at woah woah!” Sweetie said as Scootaloo shoved her butt right in her face. It’s true Scootaloo’s wasn’t quivering or radiating heat or twitching or sticky looking or anything. Sweetie still blushed at how easy it would be to just smush her face into Scootaloo. It wasn’t making her blush though, and any thoughts she had of burying her face in it or licking it were just the estrus making her mind act weird. At last, approximately 2 seconds later, Sweetie was free of her friend’s butt, and Scootaloo said,

“See? No heat!”

“I’ll just, um...” Sweetie lost her voice, pulling her tail in and squeezing her aching thighs together tenderly. And like it had done since estrus started, the squeeze kept going up all the way inside making her feel wobbly. Visions of the new colt were dancing in her head, and the dance was very provocative. “Where... is Apple Bloom?” she asked carefully.

“Um, I last saw her at the clubhouse. But I don’t think‒”

“Gotta go,” Sweetie said tightly, trotting off towards the southwest orchard.

“Wait!” Scootaloo called behind her. “I went to the skate park after that! And then we uh, ate lunch just now. I don’t know if she’s still there.”

“You mean you are telling me about something so wonderful, and now I can’t even do it?” Sweetie said, tearstruck.

Scootaloo’s face fell, and she said, “Oh no Sweetie, I didn’t mean... I mean you can... you just have to ask and...” In another uncharacteristic hug she said, “Don’t worry Sweetie we’ll help you, just you gotta be patient.”

Sweetie sighed. Their conversation had got her so excited that she was feeling hot and wet in there again. She needed more Moon tea. She needed some time to herself. She needed to just... get her wits together.

“I’m going to take a walk before class,” Sweetie said. “Alone,” she added when Scootaloo tried to follow.

“O-okay Sweetie. Sorry again; I know what that does to your body. Just... good luck cooling down.” She turned away and mumbled “Sorry,” again and buzzed off. But really Sweetie was the one who should have felt sorry, because it was the first signs that she was turning into a meanie.

Sometime days later, long after Sweetie’s experience with Apple Bloom, that wonderful night of learning just why the stallions were hugging Rarity on her bottom, it was Scootaloo’s turn to flashback again. Scootaloo was trying to console Sweetie Belle at the time, who had just confessed a terrible story about her older sister Rarity.

“I’m sure it isn’t being close to stallions,” Scootaloo said confidently. “I was so close to Apple Bloom that I think she hit my belly button in there, and all it did for me was make me all sappy and giggly. I don’t think I could get angry at somepony after that if I tried, not even Diamond Tiara.”

The two looked around fearfully for a moment but thankfully invoking her name alone would not cause Diamond Tiara to manifest in the tightly closed clubhouse in which the two fillies were confessing their deepest secrets.

“It’s not you, it’s me,” Sweetie Belle clarified urgently. “Rainbow Dash never yells at you when she’s with stallions. Applejack never yells around Apple Bloom when she... um, if she is with stallions. It’s only Rarity.” Sweetie shuddered and looked down sorrowfully as she remembered her sister in a way she never wanted to.

“She doesn’t have estrus the same way,” Sweetie went on with difficulty, “And it makes her different from other ponies so when she’s with stallions she gets... gets broken and yells at them and hides in the dark and screams at me and calls me a thief and makes me run away,”

Sweetie Belle was crying hotly at this point, and Scootaloo felt paralyzed. She just didn’t know what to do. “A-and since I’m her sister,” Sweetie forced herself to continue, “T-that means I’m the s-same way.”

“No you’re not,” Scootaloo urged, trying to reach her somehow.

“Yes I am,” she just sobbed, her tears hitting the clubhouse floor.

“No you’re not, Sweetie!” Scootaloo said demandingly. How could she even think‒

“Yes I am!” Sweetie shrieked, stopping dead as she looked straight at Scootaloo. There wasn’t a trace of anger on Sweetie Belle’s face. She just looked scared, like there was a monster behind her, or, or closer than behind her. The forgotten tears were running down her cheeks.

Scootaloo looked down darkly, saying, “If you tell anypony about this, I’ll never hear the end of it.” Then she lunged forward and hugged Sweetie Belle right around the chest. Like not even a nuzzle or a one hoof, but a double hoof full upper body bear hug. And that opened the flood gates for the poor unicorn, and they sat there for a while with Sweetie just pouring her heart out without even saying a single word.

...

“So wait a minute,” Apple Bloom said, “Ahm confused.” She adjusted her sore bum on the rope netting of the jungle gym. “Sweetie thinks that Rarity has some kinda evil estrus that makes her mean,”

“Yup, something like that,” Scootaloo said grimly.

“An’ because they’re related then Sweetie Belle has it too?”

“She totally doesn’t, but she wouldn’t listen to me!” Scootaloo said, waving her hooves in the air for emphasis.

“So why wasn’t she crying or anything?” Apple Bloom asked curiously.

“What?”

“This is Sweetie Belle. She cries when she stubs her hoof. If I was scared of gettin’ some evil thing from Applejack attackin me then I’d be cryin. Seems like Sweetie would be bawling her eyes out.”

Scootaloo curled her hooves in front of her, saying “Oh, um, I might have left out a few minor details,” her muzzle scrunching up a bit. “So what do I‒” she added hastily.

“Wait, so she was crying?” Apple Bloom cut her off.

Scootaloo was quiet for a moment, then said, “Maybe a little.”

“And what did you do?” Apple Bloom said, pulling herself up to a sitting position.

Scootaloo remained laying back and said, “Oh I might have uh, hugged her just a little, you know, patted her on the back, all... cool and stuff.” Something about Scootaloo’s cutely prone hoof curled pose, and the bright color in her cheeks indicated that it might have not been as cool and collected as all that.

Apple Bloom stared off distantly into the trees adjacent to the jungle gym, mumbling almost to herself, “She was afraid of that when she did it with me...”

“Wait,” Scootaloo perked her ears, “She actually went and did it with you?”

“Yeah, you know the whole colt thing? Ah got her estrus gone good.” Apple Bloom couldn’t help but feel smug about that. It’d only been her second time even. She was loving the buck out of this hip bucking activity.

Scootaloo sat up in interest saying, “I never thought she’d have the guts to. When did you do it?”

“It was the night after I took care a you,” Apple Bloom recalled, “She snuck all the way up to the farmhouse, just to apologize! It was the least I could do for her.”

“Apologize for what?” Scootaloo said tilting her head.

“Oh, just Sweetie went and threw a huge fit when she couldn’t be around me. She tracked me down after school it turns out, looking to cure her estrus no doubt. I didn’t know it and told her I’d be a filly again and she just‒”

“Flipped her lid?”

“No, she just got sad at that and wanted to know why. In fact she only flipped her lid when her sister... well her sister and Twilight both helped take her away from me.”

“Why’d they do that?” Scootaloo asked, befuddled.

“Ah don’t entirely know, but it’s something about me bein a colt. Maybe they’re worried about the same thing she is. I mean, I ain’t never seen her so mad before, and it was all over nothing but a silly time out.”

“Well she did think you were going to turn back into a filly without curing her estrus,” Scootaloo offered.

Apple Bloom nodded, “Yeah that’s enough to flip your lid I’d say. Still ah don’t want to make her crazy mean, if she’s got some kinda genetic pro-clivity for it. What do you think, Scoots?”

Scootaloo tapped a hoof against her jaw, then said, “Was she getting angry after you put your penis inside her?”

Apple Bloom blushed at the thought of that. A sixth time and she still wasn’t getting used to this putting your penis in fillies thing. “N-no, she‒” Apple Bloom stopped talking as she actually thought about it.

“You know,” Apple Bloom concluded, “She wasn’t gettin angry at all!”

“So your boy stuff didn’t make her mean?”

Apple Bloom laughed relievedly. “She was rollin on the floor she felt so good. It was so adorable! Said she felt ‘fuzzy’ inside. I tell you she’s pretty fuzzy on the outside too.”

Scootaloo laughed at that too. Sweetie was admittedly a perfect little white ball of fuzz if you looked at her in the right light.

“I wonder why she was so afraid of you the next day then,” Scootaloo wondered. “She can’t have forgotten something like that.”

Apple Bloom paled a little and said in a very apologetic tone, “Oh, ah might have uh... brought up the fit she threw, after we were done. How could I have been so stupid?! Acourse that was gonna upset her.”

“It’s okay, you didn’t know,” Scootaloo assured her.

“She even cleaned up after me without even askin,” Apple Bloom went on guiltily, “Said she wanted to do something nice for me, for making her feel so good.”

“Wow,” Scootaloo said, “And I thought I felt sappy when you did it to me. If you call that angry, then my reaction was angry as Azuihotl was when Daring Do managed to tie his tail to the Pillar of Woe.”

“Azu-who?”

“Ugh,” Scootaloo said rolling her eyes, “Only the coolest villain ever to match wings with Daring Do.”

“Oh I uh haven’t read that one yet,” Apple Bloom said laconically.

“You totally should,” Scootaloo said, “I thought reading was boring until Rainbow Dash showed me that she reads it!”

“So, what you’re trying to say is, Sweetie Belle...” Apple Bloom said to start, and Scootaloo finished the sentence for her, with a frustrated kick at the netting.

“...has got nothing to worry about!”

The two of them clambered off the jungle gym and headed back to the school yard, ignoring the other ponies for now. Apple Bloom got a few eyes from fillies but she waved ‘em off. She couldn’t help much since she already put her boy stuff in Liza today. Apple Bloom made another mental note to get those other colts in gear as soon as possible. She didn’t want a filly to have to wait even a day to get their estrus dealt with.

“We gotta do something though,” Scootaloo said while they trotted back towards the schoolyard. “Sweetie Belle is killing herself over this! You should have seen her when‒ I mean wow, but she was‒”

"But how to reach her?" Apple Bloom sighed, "She won't even talk to me, and you, well...”

“...well what?”

“Well it’s just you’re kinda uh...”

Scootaloo just eyeballed her dangerously.

“Uh... never mind.”

By the end of the day Apple Bloom was more than ready for next week’s Geology exam. It certainly wasn’t hard to tell a lith crystal from a granite seed. The last year’s exams were much harder than these, if she recalled correctly. As she walked with Big Macintosh she pondered if maybe there was a good reason for this. It was their first heat after all, and the entire class filly population was all synchronized with it. Maybe Cheerilee was going easy on them?

A corner of her mouth turned up smugly as Apple Bloom remembered at least six fillies who wouldn’t have any problem with exams because of her, and counting! She had a bit of a spring in her step on the way down with Big Macintosh to Dinky’s house. Apple Bloom had pumped Liza Doolots full of boy goo this morning, but she made sure to have a big lunch with plenty of milk and avoid any overeager fillies that afternoon, and by the end of the day she felt ready and eager to take on another. She felt sort of full and tickly down there, with just a hint of internal tension. If that wasn’t boy stuff ready to come out then Apple Bloom was a one eyed pickle.

It was with an eagerness that surprised her, Apple Bloom imagined the pleasant act of putting boy stuff in the whole way there. She might really be a filly inside, but this afternoon at least she could think of nothing more appealing than being a colt, and doing with a filly what a colt is supposed to do to a filly’s estrus. The studying seemed almost secondary to the act of pumping stuff right deep into a vagina, like it was a minor bonus to a major act, even though the studying is what she was going there for. Apple Bloom’d probably remember doing it with Dinky far more than whatever they were going to be studying afterwards. She had to bite back a snicker when she realized the boy thing technically was a form of studying. Studying the inside of a filly’s bottom that is.

She wondered what Dinky would be like. They were in different classes, so Apple Bloom had only seen the unicorn in passing before. Just your ordinary magic purple unicorn. The blonde mane was a bit rare, though. Well, it couldn’t be a bad experience at least. Dinky was a filly in heat just like anypony else, with the same two soft buttons and the one hot button. And it’s not like Apple Bloom was going to visit Diamond Tiara or anything. Dinky always looked so cheerful, but Archer had implied maybe she was more serious than she put out in front of her. It’d be interesting, to say the least.

Big Mac didn’t seem nearly as eager to let Apple Bloom go to Dinky’s house as she was. Especially when it was a mare who answered the door. That mare to be specific. But when she was followed by a chipper brown stallion who stood by her supportively, Big Macintosh relaxed. Dinky squeezed between the two and zipped up to see Apple Bloom with a bright, friendly smile. Dinky didn’t say hi or anything though, just kept on smiling. Mac gave Apple Bloom a little nudge then, and the deal was settled, and she followed the Dew family into their house.

It was a two story house they lived in, with a nice basement. Seemed a little big for just three ponies, but apparantly there was a fourth one out on an exploration mission at the time.

“Your friend Archer is still upstairs,” the stallion said in a pleasant tenor, vaguely remniscent of Trottingham, “There’s some cookies and punch if you get hungry. If you need any help, I’ll be in the workroom downstairs.”

“And I will be delivering the mail!” the grey mare said exhuberantly, in a tone that made Apple Bloom think of wrinkly bald rats for some reason. She already had her saddle bags on, and a snazzy looking if a bit oversized delivery cap on her head.

“Thanks for having me, Mr. and Mrs. Dew,” Apple Bloom said congenially before the mare could head off, “I’m really looking forward to helping your daughter out. Sorry to hear she was struggling on her own, but with me and Archer here, she should be all taken care of far as studying goes before the sun goes down!”

“Awwww,” Mrs. Dew said, putting a hoof down and rumpling up Apple Bloom’s hair. “Aren’t you just the gentlest little stallion.” Apple Bloom hadn’t been wearing her bow these past couple of days. It just didn’t fit right with her new colty physique. One look in the mirror was enough to determine that. She needed a scarf or something, or maybe a tail bow.

“Shucks, ma’am” she said, blushing.

“Oh, but we’re not married though,” Mrs..... the mare said. “My last name is Dew though, but a nice colt like you can call me Dipsy!”

“Dinky is my daughter, and he’s my,” Dipsy said zipping right up to Apple Bloom, whispering with barely restrained glee, “Boyfriend!”

“I’d ask for your hoof in marriage my dear,” the stallion said, “But I’m afraid I’m rather fond of the name Turner.”

Dipsy squealed delightedly and danced over to him, planting a kiss on his cheek, which led to a kiss on the lips, which led to a liplocked embrace with their front hooves held together. They pulled back from that and Dipsy waved one more time before flying out the door, barely even cracking the frame as her ass bumped against it. Apple Bloom was watching the mare and stallion with one raised eyebrow, and Dinky was still ...smiling at Apple Bloom. Huh. But if that is how a kiss was done, then Apple Bloom had been doing it wrong this whole time!

“Ahem, yes well,” Turner said, embarassed at Apple Bloom’s attention, “Dinky can show you upstairs, where you can study with Archer. There’s um, cookies and punch if you get hungry. And without further adieu, I will be in my workroom!” With a melodramatic flourish he threw open the basement door and clambered down it letting the door swing shut behind him.

Apple Bloom looked at Dinky for some idea of where to go at this point, but Dinky wasn’t saying... anything. So Apple Bloom just went upstairs on her own, followed by the little unicorn. It was odd now that Apple Bloom thought on it, why would a pegasus and an earth pony have a unicorn foal? Probably a good explanation for it somewhere. Apple Bloom wasn’t exactly sure how ponies were supposed to mix genetically though. They sure didn’t fertilize each other like plants, but the baby ponies still came around somehow. Just, as in Dinky’s case, sometimes it didn’t make a lick of sense.

“Hey!” said Archer, after Apple Bloom found the door, “You’re here!”

“Yeah uh,” Apple Bloom walked herself into the room they were in, a filly’s bedroom it looked like, most likely Dinky’s. There were some papers set up and a pile of newsprint, some hefty textbooks on the bed with pink sheets and a lavender comforter. The smell of estrus was thick in here, made Apple Bloom’s nose twitch, and made her take in a nice long breath. Dinky definitely needed it, if this was her scent. An overhead lamp cast a calm glow over everything.

“I think there’s something wrong with Dinky here,” Apple Bloom said to Archer, walking in through the door. Dinky was still smiling at her and... otherwise completely unresponsive.

Archer just snorted, saying “Yup, this is my friend Apple Bloom.” She laid a hoof casually over Apple Bloom’s shoulder, who smiled at her out of the side of her face awkwardly. “Just another ...study buddy,” she said chipperly, “Guaranteed to make your studying problems go away!”

There was a pause. Archer took her hoof off of Apple Bloom, standing there uncomfortably then saying, “Um, sorry. Was it too much?”

Still no response. Apple Bloom waved a hoof in front of the unicorn’s face. That managed to snap her out of it, but instead of saying hi she just marched past Apple Bloom and straight up to Archer, then hissed loudly into Archer’s ear,

“You didn’t say Apple Bloom was going to be a colt!”

Archer smiled and replied giddily, “I know, isn’t it great?”
